Study Notes
Network Basics
- The main function of a network is to connect devices and facilitate communication between them.
Types of Networks
- A LAN (Local Area Network) connects a small number of systems in a relatively close geographical area.
- The Internet is commonly referred to as a WAN (Wide Area Network) that spans a large geographical area.
- A MAN (Metropolitan Area Network) connects several LANs in a metropolitan area.
- WAN (Wide Area Network) typically spans a large geographical area, such as a city or country.
Internet Characteristics
- The Internet's main protocol suite is TCP/IP, which enables linking various types of electric devices worldwide.
- The Internet's primary characteristic is its ability to connect devices and allow communication between them.
Communication System Components
- An input transducer converts input data into a signal that can be transmitted.
- The receiver receives the signal and converts it back into the original data.
- The transmitter sends the signal to the receiver.
- The information source provides the data to be transmitted.
- The channel provides a physical connection between the transmitter and receiver.
- The destination receives the transmitted data.
Data Transmission Modes
- Half-duplex mode allows data transmission in both directions, but not simultaneously.
- Simplex mode allows data transmission in one direction only.
- Full-duplex mode allows data transmission in both directions simultaneously.
Network Characteristics
- A broadcast network provides a capability where several receiving stations can be reached simultaneously from a single transmitter.
- The Internet is a network of networks, connecting multiple networks and devices worldwide.
Key Concepts
- The basic elements of a communication system are the information source, transmitter, channel, receiver, and destination.
- The basic components of a communication system are the input transducer, transmitter, channel, receiver, and destination.
- The main difference between a LAN and a MAN is the geographical area they span, with LANs covering a smaller area and MANs covering a larger area.
